The frequency of the second class is 6.
Since the class width is 6 and the lower limit of the first class is 50, this means the first class goes from 50-55. This would put the second class at 56-61. There are 6 data points in this set that would go in the second class.

Answer:
It took 5 hours to repair the car
Step-by-step explanation:
An auto repair shop charged a customer $349 to repair a car.
The bill listed $99 for parts and the remainder for labor.
The cost of labor is $50 per hour. If the number of hours it took to repair the car is x, then:
99 + 50x = 349
To find the number of hours it took to repair the car, we need to find x:
50x = 349 - 99
50x = 250
x = 250 / 50 = 5 hours
It took 5 hours to repair the car.
The total expenditure is Rs 72,000.
<h3>
What is the total expenditure?</h3>
The total expenditure can be determined using this equation:
(total amount spent on a good x total value of circle) / degree of the sector of good
(8000 x 360) / 40 = Rs 72,000

C
given x² + 16x = 41
to complete the square on this equation
since the coefficient of the x² term is 1
add (half the coefficient of the x-term )² to both sides
x² + 2(8)x + 64 = 41+ 64
(x + 8 )² = 105 → C
